FOUNTAIN-PEN.

SPECIFICATION forming part of Letters Patent No. 564,842, dated July 28, 1896.

Application filed March 12, 1896.

To @ZZ wiz/m tmwy concern:

Be it known that'I, CARLA J. RENZ, of Ne York city, in the county and State of New York, have invented a new and Improved Fountain-Pen, of which the following is a full,

clear, and exact description.

The object of my invention is to provide a fountain-pen so constructed that it will write to the last drop of ink, without danger of leaking, and in which the flow of ink can be easily and instantly regulated to suit the'writer, or stopped entirely, enabling the pen to becarried point down in the pocket with absolute safety.

A further object of the invention is to construct a pen having the advantages above set forth in an exceedingly simple, durable, and economic manner, and, furthermore, to provide means whereby should the ink at the pen-point or adjacent to the same become in any manner dry the iiow of ink may be instantly started the moment that the pen is placed in position to write.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had tothe accompanying drawings, forminga part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure lis a side elevation of the pen closed. Fig. 2 is a side elevation of the pen, the point being nncapped. Fig. 3 is a longitudinal vertical section through the major portion of the pen, the feeder being in'position to admit the writing fluid to the point of the pen. Fig. is a longitudinal section through the pen in its entirety, illustrating the feeder in position to close communication between the ink-chamber and point of the pen. Fig. 5 is a transverse section taken, practically,on the line 5 5 of Fig. 4. Fig. 6 is a similar section taken on the line 6 6 of Fig. 4. Fig. 7 is a transverse section taken on the line 7 7 of Fig. 4. Fig. 8 is a plan view of the feeder removed from the pen. Fig. 9 is a bottom plan View of the aforesaid feeder; and Fig. 10 is a longitudinal section through the feeder, taken practically at a central point.

In carrying out the invention a barrel A is constructed of suitable size, adapted as a res- Se'rial No. 582,867. (No model.)

ervoir for the ink, and the said barrel at its upper end is closed by a cap B, whichis'held in the barrel by frictional Contact, or through the medium of screw-threads, as illustrated, and the cap B is preferably provided with an air-vent l0, as shown in Fig. 4, the barrel being lled with ink upon the removal of the aforesaid cap.

A plug C is either screwed `into the lower end of the barrel or held liquid-.tight therein by frictional contact, and the said plug is hollow and is provided between its ends with an exterior collar ll, serrated or otherwise roughened to facilitate the removal of the plug from the barrel of the pen. The bore of the said plug isreduced at its upper or innerend, forming avent-opening l2, and at its outer end the plug is preferably interiorly threaded to receive a nozzle D, exteriorly threaded to meet the threadsof the plug; but the nozzle and plug may be connected in a Huid-tight manner by frictional contact, if so desired. When the plug is secured in the barrel, the collar 1l of the same will engage with the bottom portion of the barrel, as shown in Figs. 3 and 4.

The fountain-pen isprovided with a feeder E and a nib or pen E', the Ynib or pen E being adapted to be introduced into the nozzle D, the said nozzle being tubular, and the feeder E is adapted for engagement with the pen or nib and is of such length that it will extend through the` nozzle and vthrough the plug() into the ink-receiving chamber of the barrel A, as shown in both Figs.V 3 and 4.

The feeder E comprises a body e, a shank e', and ahead e2, the latter being at the inner extremity of the shank. The shank is circular in cross-section, as is likewisethe body e, but the aforesaid' body is of greater diameter than the shank and is made to taper in direction of its outer end. The point l2 of the body of the feeder is flattened upon its under face and is of less Athickness than the remaining portion of the body, as shown in Figs. 9 and 10. The point l2 has a number of perforations 13 made therein, and is provided upon its upper face with a series of grooves 14, extending longitudinally ofthe aforesaid feeder, thel grooved portion of the point being adapted to be brought substantially in close contact with the under face of IOO the nib or pen E. The perforations 13 constitute air-passages, by means of which the ink is forced to the elevated or ribbed surface of the top of the point of the feeder formed by the grooves 14, and the ink will be compelled to flow on both sides of the point of the feeder at the top to the extremity of the same, ready for distribution through the medium of the nib or pen E.

The body portion e ofthe feeder has a series of basins 15 made Jtherein transversely at the top and bottom, the bottom basins being immediately below the top basins, and each top and bottom basin is connected through the medium of an opening or aperture 16, as is best shown in FigflO. These basins serve as reservoirs for the ink, and the ink is retained in the said basins air-bound by the aforesaid openings or perforations 1.6, being withdrawn by suction due to opening or closing the pen-point when the 'pen is to be used, since, as shown in Fig. 4, the feeder is held firmly yet removably in the nozzle D, and by screwing the nozzle upwardly the head of the feeder will be carried in direction of or away from the vent-opening 12 in the plug,

. through which the shank of the feeder is loosely passed. When the feeder is drawn outward from the barrel, a washer 17, attached to the shank of the feeder at the head, will be brought more or less closely against the inner end of the plug C, regulating the supply of ink from the reservoir of the bar rel to the feeder, and when the said washer is brought in close engagement with the plug C, as shown in Fig. 4, the supply of ink to the feeder will be entirely cut off, so that the pen may be carried point downward, or carelessly handled with impunity, yet there will be sucient ink air-bound in the basins 15 to admit of a letter of ordinary length being conveniently written without a further supply, and the ink in the basins being air-bound will not flow to the pen-point unless the said point is pressed upon the paper upon which the letter is to be written.

At each side of the feeder a groove 18 is preferably made, which serves to admit air to the feeder and facilitate the flow of ink along the same to itspoint, and, if in practice it is found desirable, near the inner end of the body of the feeder an annular basin 19 may be formed, and an opening 20 is then made in this basin, extending from top to bottom of the feeder. Vhile in the drawings the shank e of the feeder is shown as provided with a spiral groove 2l, the said groove may be omitted if in practice it is found desirable and simply a channel 22 formed in the inner end of the body of the feeder to admit rof the writing Huid being conducted to the basins of the said feeder.

The pen or nib E is insured a proper position upon the feeder by reason of the inner end of the pen or nib being brought in engagement with a saddle 23, formed upon the upper face of the said feeder, as is particularly shown in Fig. 4, and a loose collar 24 is mounted upon the shank e of the feeder, and the said collar will be contained within the plug C, so that when the pen is brought to writing position the collar in sliding along the shank will force the ink contained in the basins 15 to the point of the pen in the event that the ink should become dried and will not ow of itself to such point, and, if a single downward movement of the pen is not sufficient to accomplish this result, on moving the pen quickly forward and backward the collar will accomplish said result.

It is evident that, by reason of the adjustment of the feeder to and from the barrel ofv the pen, the ink may be made to ilo-w more o1' less freely to the point or nib of the pen and that the supply of ink may be entirely cut oif when desired, thus enabling the pen to be carried point down without .danger of spilling any of the ink that may remain between the barrel and the nib, owing to the ink in the various basins 15 being air-bound until forced to flow to the point of the pen either by the action of the sliding collar 24 or by the flexing of the nib of the pen.

The longitudinal airy-vents 18 are not at the exact center of the feeder, being rather below the center, and connect with the lower basins, whereby the air-pressure serves to force the ink upward into the upper set of basins. The

sliding kcollar 24 may be dispensed with, if so y desired, although it is preferably used, and in such event the body section of the feeder will be made much larger than illustrated.

Having thus described my invention, IV
